What is the use of ErrorProvider Control in .NET?

Answer Posted / saravankumar

The ErrorProvider control is used to indicate invalid data
on a data entry form. Using this control, you can attach
error messages that display next to the control when the
data is invalid, as seen in the following image. A red
circle with an exclamation point blinks, and when the user
mouses over the icon, the error message is displayed as a
tooltip.
